Real-time measurements and their effects on state estimation of distribution power system
This paper aims at analyzing the potential value of using different real-time metering and measuring instruments applied in the low voltage distribution networks for state-estimation. An algorithm is presented to evaluate different combinations of metering data using a tailored state estimator. It is followed by a case study based on the proposed algorithm.
A real distribution grid feeder with different types of meters installed either in the cabinets or at the customer side is selected for simulation and analysis. Standard load templates are used to initiate the state estimation. The deviations between the estimated values (voltage and injected power) and the measurements are applied to evaluate the accuracy of the estimated grid states.
Eventually, some suggestions are provided for the distribution grid operators on placing the real-time meters in the distribution grid.
